As I explained, it is not ALL about that, it's ALSO significantly harder and time-consuming to produce. Whether or not the different material is worth the higher price to you is another question entirely.
I am not sure I understand the point being made. OP asked a question about a specific price points not why it was higher price in general (which may make sense with your earlier statements). Of course I can only speak for myself, I can't tell what this watch is worth to you or anyone else. I can only say for me I would never pay that much for the watch when its casing is going to last decades scratch-and-scuff free over the internals which would only last a few years at best. That only makes sense for a luxury mechanical watch in my mind.
Your original statement stated that the price was almost reasonable for this watch, I disagreed. Just because Apple decided to utilize a process and material that takes longer doesn't mean I am inclined to pay that much for it. I believe Apple is upselling their watch to that price point simply because they know people will buy it, and using statements such as scratch proof and multiple-day process as justification.
